Truss, Sunak or whoever comes next must harness the angry anti-establishment mood of centre-Right voters or be swept away by a Labour Party promising, however implausibly, that it is “time for change”. The next leader will need to make good on the promise of Brexit, not merely on its legalities. They cannot keep going with Johnson’s idiotic war on his own supporters, his green fundamentalism, profligate extravagance and gimmicky levelling-up that will achieve nothing but waste billions of pounds of taxpayers’ money.
